[wuxiaohua1011]

on line 86 and 87 in stereo_camera.py, the code
left_frame = frame[:, : width/2, :] and right_frame = frame[:, width/2:, :] should be
left_frame = frame[:, :int(width/2), :] and right_frame = frame[:, int(width/2):, :]

i have Macbook Pro and its reporting
TypeError: slice indices must be integers or None or have an __index__ method without those

Seems reasonable. Would you like to send a PR that implements this? This might also be a Python2 vs Python3 issue, as Python2 probably implicitly casts floats...
